In these areas, conventional water sources such as snowfall, rainfall, river runoff and groundwater are rare if not completely absent. But innovative water sourcing methods could help address that scarcity.
In an article for
Conversation, environmental scientists Manzoor Qadir and Vladimir Smakhtin, both from
United Nations University in Japan, detailed five water harvesting techniques that tap into unconventional water sources such as fog and saltwater. These techniques require advanced technologies but could help meet water demand in arid and remote regions.

India has 4,407 large dams of which more than 1,000 would be 50 years or older by 2025, a new study has shown. Older dams pose greater safety risks, cost higher in terms of maintenance and have declining functionality due to sedimentation, stated a study by the Canada-based United Nations University Institute for Water, Environment and Health, released in January. Climate change is also likely to accelerate the ageing of dams, it said.
